The Quebec Marine Mammal Emergency Response Network: case in
progress
October 12 2007: a St. Lawrence beluga whale is present in the Saguenay
River, beyond its typical range.
Recent developments
- 31 October 2007: Still no sign of Dl 247. A team
made up of GREMM and Saguenay-St. Lawrence Marine Park employees patrolled
the Saguenay Fjord from Tadoussac to Leste Cape today. They came across
several groups of beluga whales, however Dl 247 was not among them.
Observation conditions deteriorated late in the morning. Search efforts
will come to an end when, on Thursday and Friday, a land-based observer
verifies the area frequented by the beluga whale before its disappearance.
GREMM researchers will keep an eye out during regular monitoring of this
population next summer. They may spot Dl 247 where it was normally
observed since 1991: in the Saguenay and on the edges of the mouth of the
Fjord. Its carcass may possibly wash up in the coming days or weeks. A
post-mortem examination would be extremely useful from a scientific point
of view. We therefore invite the general public-who may spot the beluga
whale near Chicoutimi, or a carcass anywhere in the region-to contact the
Network at 1-877-722-5346.
GREMM would like to underline the remarkable effort of Quebec Marine
Mammal Emergency Response Network partners Fisheries and Oceans Canada, the
Centre québecois pour la santé des animaux sauvages (CQSAS), the
Saguenay-St. Lawrence Marine Park and the St. Lawrence National Institute
of Ecotoxicology. Their expert consultations, media coverage, potential
interventions planning and monitoring in the field were greatly
appreciated. Furthermore, a special thanks goes out to Mr. Gérald
Mercier, a fisherman who first reported the incident to the Network Call
Centre. Day in, day out, his precious collaboration was essential in
monitoring the situation.
- On Saturday, October 27, our observer, Mr. Mercier, reported that after
a detailed search of the area that had been the its hangout for the past
two weeks, the beluga whale had disappeared.
The most probable hypothesis is that Dl 247 took advantage of the
strong tides on Friday and Saturday to swim downstream.
A team composed of GREMM and Saguenay-St. Lawrence Marine Park
personnel patrolled the area between Saint-Fulgence and Chicoutimi from
aboard a boat, and both shores upstream of the Chicoutimi Bridge on foot
and in a car. No sign of the beluga whale.
Other patrols will take place over the coming week in an attempt to
spot Dl 247 in the River or Fjord. The general public is invited to keep
an eye out and to report any sighting of the animal, alive or dead, by
contacting the Quebec Marine Mammal Emergency Response Network call centre
at the following number: 1-877-722-5346.
Case summary
On Saturday, October 13, the Quebec Marine Mammal Emergency Response
Network Call Centre received information concerning the presence of
a beluga whale near the Shipshaw Dam in the
Saguenay River, upstream from the typical St. Lawrence beluga whale range.
This is a first, if not a very rare, case. Due to the lay of the land, the
interplay of the tides and the characteristic beluga whale behaviour in
similar circumstances, it is highly unlikely that this whale will leave the
area on its own. It is quite thin, and it is very likely that this
condition predates its arrival in the Saguenay River.

Dl 247
The GREMM
(Group for Research and Education on Marine Mammals), which is currently
conducting long-term research on the St. Lawrence population, has managed
to identify this beluga whale. Code number Dl 247, a male that was
identified for the first time in 1991, is at least 30 years of age. Dl 247
belongs to a network of male beluga whales that regularly frequent the
Saguenay Fjord.
What is being done to help this animal?
After consulting with experts who work with similar networks elsewhere
in the world, partners of the Quebec Marine Mammal Emergency Response
Network have concluded that it is preferable not to intervene directly for
this animal in the present context. The beluga whale is in very bad
condition and scientific experts estimate that it has little chance of
recovery. Any direct intervention, such as an attempt to move him for
example, would impose a significant amount of stress that could exacerbate
his present condition. In this case, it has been deemed best to let nature
take its course. For now, the option of euthanizing the whale has been
set aside. The natural capacity of marine mammals to recover is
surprising. It is not impossible that the whale, left in peace, could
survive this adventure.
This decision is consistent with Network guidelines. The Network
includes
governmental institutions and private Quebec-based groups working with
marine
mammals, such as Fisheries and Oceans Canada, The Saguenay-St. Lawrence
Marine
Park, CQSAS (Centre québécois pour la santé des
animaux sauvages) and GREMM.
Network guidelines that justify this decision
Guidelines were established during the 2002 workshop on marine mammal
interventions that led to the creation of the Quebec Marine Mammal
Emergency Response Network. These extensive consultations included
government ministries, government agencies and private organisations
involved in these types of interventions in Quebec, along with invited
experts in the fields of ethics and emergency intervention for marine
mammals.
The network will intervene:
- When humans have caused the animal's situation;
- When the animal belongs to an endangered
species
and there are chances for its recovery; and
- When the intervention will lead to the acquisition of scientific data
without prejudice to the animal's well being.
Costs, logistics and the security of field operatives are also taken
into consideration.
The next steps for Dl 247
Fisheries agents have been on site since October 23 to ensure that the
beluga
whale is not disturbed. Beluga whales are protected under Canada's
Species
at Risk Act (SARA),
which states that they are not to be disturbed.
We are therefore asking people to avoid navigating in the area,
if possible, not to approach the beluga whale or to feed it. The
additional stress
could prove fatal for this whale.
A Network team will monitor the situation; observers will be dispatched
and veterinarians will evaluate the animal's state of health. Based on
these reports, the Network team will re-evaluate the situation and the
line of conduct on a weekly basis.
If the beluga whale dies, a necropsy will be conducted in order to
determine the cause of its feeble condition. This examination will be
carried out within the context of the beluga whale carcass recovery programme, a
scientific study that began in 1982 and is presently headed by Fisheries
and Oceans Canada in collaboration with the University of Montreal's
Faculty of Veterinary Medicine and the St. Lawrence National Institute of
Ecotoxicology.
If the animal becomes stranded, it will be a sign that it is very weak
and is condemned to die. There will be no attempt to return it to the
water, however it will be euthanised.
If the animal's state improves markedly, the option of a direct
intervention to help it leave this portion of the River will be
re-evaluated.
